20 Claims.

This invention relates to railway car trucks and more particularly to means for mounting thereon brake beam guards, guides, or support structures.

There is an increasing tendency in railway truck construction to decrease the weight of the truck by eliminating the spring plank which usually extends between the side frames and mounts the bolster springs and, frequently, mounts the brake beam supports and safety guards. In some old trucks the portions of the spring planks intermediate the side frames are being cut out, the end portions of the spring plank, or similar structure, being retained and utilized as seats for the bolster springs and for attachment of a transverse tie bar extending between the side frames.

An object of the present invention is to mount brake beam guard, guide, or support structure upon the spring seating structure.

Another object is to secure the end of the spring plank or bolster spring seat to the side frame so as to maintain the parts assembled when the bolster springs are removed.

A more detailed object is to attach a brake beam guard, guide, or support device to a ledge or web projecting inwardly from the truck side frame, or other part, so as to support the device without relying upon rivets or similar attaching elements.

These objects and other more detailed objects hereafter appearing are attained by the structures illustrated in the accompanying drawings, in which- Figure 1 is a transverse sectional view through the side frame of a railway truck embodying one form oi the invention.

Figure 2 is a top View of the structure in Figure 1 with the bolster springs omitted.

Figures 3, 4, 5, 6, 8, l1, 12, 14, 15, 16, 17, and 18 are views similar to Figure l but illustrating various modiiications.

Figure 7 is a partial top view of the structure in Figure 6.

Figure 9 is a top View of railway truck parts illustrating a different form of brake beam safety guard device.

Figure 10 is a transverse vertical section taken on the line IG-IU of Figure 9.

Figure 13 is a top View of the structure in Figure 12.

Figures l and 2 show the lower center portion I of a well known form of railway truck side frame having a central opening for receiving the bolster springs 9 and the end of the bolster (not shown). Framing member I includes a substantially horizontal web 2 projecting laterally in each direction (o1. 18s-zio) from the side frame, as at 3 and 4. Mounted on top of the web 2 is a channel member including the vertical flanges 5 and horizontal web G, recessed as at I for interengagement with the boss 8 on the framing web 2 for holding the channel 5 member in position. Seated on the web 6 are the coil springs 9 for supporting the end of the bolster (not shown) as is well known. The channel spring seat member may be conveniently formed from the end portion of an ordinary channel spring plank.

Located inwardly of the side frame member l is the bracket I0 mounting the brake beam guard, guide, or support strap I I between the flanges i2 by means of pins, one of which is shown at I3. The member I I is disposed inwardly, as at I4, and then longitudinally for association with the brake beams.

Bracket III includes the outwardly projecting jaws I5 receiving .therebetween the inner extremity of ledge portion 4 of the horizontal framing web 2 and a lip IB extending around and over the inner extremity of the channel web 6 and secured thereto by rivets II. The web 6 is bulged at I8 to accommodate the upper bracket jaw I5. The guard, guide, or support member and its supporting bracket are wholly carried by the jaws I5 and lip I6, the rivets I'I functioning solely to maintain the assembly.

At the outer extremity of the framing hori- 3-0 zontal web2 is a lip I9 hooked over the correspending extremity of channel web 6 to assist in maintaining the spring seating channel in position in case the bolster springs are removed.

In Figure 3, channel spring seating member 2Q rests upon the horizontal web 2| of the side frame bottom member 22, as in the previous form. The guard, guide, or support bracket 23 is attached to the inner extremity of the channel 2B by means of a rivet 24 and a lip 25 hooked over the inner extremity of the channel horizontal web. A shortv lug or rib 26 is provided for attachment of the side frame tiebar 21 which tends to maintain the channel 20 in position on the side frame web 2|. No hook is provided at the outer extremity of the seating channel for stabilizing the assembly.

In this form, a pair of guard, guide, or support members 28 and 29 are shown attached to the bracket 23, the upper member 28 preferably being of resilient structure and disposed inwardly as the member II in Figure 2 for engaging suitable bearings on the associated beams. The lower member 29 may be of rigid structure for reinforcing the upper member and may extend di- VVandvsecured thereto by rivets 33. e

The form in Figure 4 is, in general, similar to that in Figure'3 except that the bracket 30 isk provided with coextensive jaws 3| receiving vthe inner extremity of the'channel horizontal web 32 The jaws 3| in Figure 1independentlyV of thev attaching rivets 33. Y

' Y In Figure 5, the flanged bracket 34 for the f guard, guide-,or support member (notshown) is attached to the horizontal web 35 of the bolster lip 31 integral with the guard,oguide, orsupport bracket and hooked over the inner extremity of web 35. VNo sideframe tie baris provided, as in VFigures 3 and 4,5and the outer extremity of the horizontal web 38 on the side frame memberiSS isprovided with a lip 40 hooked through the recess 4| in the body of the spring se'atweb 35 for maintaining the e channel *member and guard, guide, or support in position in casel thev bolster springsY (not shown) are removed.

In Figures 6 and '7, the bracket 42 is attached toV tlrir-:JspringV seatr channel 43 by the rivets 44. A lip 45Vpunched fromr the body of the web portion 46 of the spring seat channel is hooked through Y Va recess 441 in the sideframe horizontal web 48 for maintaining the member`43 and bracket 42 in position. f4' .l 1 Y Y 'l Figure 8 illustrates aV special form of Yspring seat channel49 having the flanged brake beam guard,l guide, or support bracket 50Yan'd thelu'g V5| for attachment of the tie bar 52 formed inte-v gral therewith. A' vertical 'rib 53Y reinforces the inner portion nel ,member includes the jbosses for positioning the bolster springs, and the `elements 5S Vand 51 cooperate with corresponding recesses in the side frame horizontal web member 58 for positioning the channel( member. At'theouter extremity of the channel member 49 isY a hook 59 extending around and beneath the Vouter'extrem- Y ity ofthe framing web 58 and preventin'gtilting of the channel member '49 Vdue tothe weight of the guard, guide, (or support structure' at the inner end thereof Vin case Vthe bolster springsv (not shown) and the tie bar 52`are removed.

In Figures9 and 10, the truss-type brakebeams 60 are safeguarded'b'y means of a Vrodtl secured tothe beams by clips 'V62 and extending above the hookedrinner extremity 03 of the spring .seatingV channel .-04which portion isjbentto cooperate Ywith rod 6|. VRod 5| also mounts Vcoil springs 65 functioning as brake beam releases. A lip Vat the outer extremity of the horizontal web Yportion 61 oftheV channel 54 is bent around and beneath the Ycorresponding portion ofthe framing horizontal web B8. The4 typeof brake beam safety guard illustrated in Figures 9 and 10, aside fromthe especially formed Vchannel member |54, does not constitute the present invention; Any suitable brake beam guard, guide, or .support dey vice may 'berprovided If desired,'the hook element63l may beseparately'formed andsecured to the inner end of the spring seating member.

In Figure 11, the inner 'extremity of the hori# zontal webportionV 690i the spring seating channel 10 Vis bent downwardly at 1| and cooperates with an angle 12 secured to the web 69 by rivets 13, or other suitable means, to form afiange'd bracket for mounting the brake beam guard,

ofthe springseat channelV above rectlybeneath .the brakebeams as a safeguard guide, or support members 14 therebetween.y The Vouter extremity of spring seating web Y69 is hooked downwardly around the Vframing web V15,

as in Figure 10. Y 4

In Figures 12 and 13, the inner extremity of the horizontal web portion 16'of the spring seating channel 11 is doubled outwardly upon itself, asv atV Y 18, forgripping the brake beam guard, guide, or Y l support strap 19, the assembly being maintained by the vertical pins 80. The channel member 11 is stabilized by the hook 8 I. v

In Figure 14, the bolster spring seating channel 82 is provided with a downwardly bent anglerBB forming a bracket for mounting the angular'V brake beam guard, guide, or supportmember 84. Tie bars, as at 85, are hooked into the spring s eating Ychannel at the sides of the bracket portion 83. f

In'Figure'lS the brake beam guard, guide, or

Support angle 86 is resiliently supported by coiled vsprings'as that at 81 carried by the bolt 88de# Y directly support the brake beam guardgguide,

or support, or its bracket, as in the previous structures. Formed integral withthe flanged bracket 9| is thehorizontal web 92 resting on top ofthe horizontal web portion 93 of the channel member SEland constituting a seat for the bolster springs (not shown). VAlso formed on the integral spring rseat and lbracket structure is the reinforcing ribV 94 and lug 90 for attachment of the tie bar91'.

Theouter extremities of the webs 92 and 93V and the framing web 98 are secured together by a U-'shaped clip or'bracketp 99 riveted in place.

The clip 979 holdsthe members90, 9| and 93 1in position'in case thebolster springs (not shown) .40

are; removed as do the hooked lips in various forms vpreviously described.) I

*Figure 17 shows a resilient brake'be'am guard,

guide, or support strap |00 reinforced by the rigid angle safety guard |0|, both being carried from the inner 'extremity of thehorizontal webportion 445 |02 of the bolster spring seating channel v|03 by I' means of a U-shaped'clip |04 similar" to the clipV 99 in the previous figure. The'clip |04 is secured in position by Yrivets |05."V 1 t In Figure 18, the ilanged bracket l'o` is riveted to the inner extremityofthe horizontal web portion |01 of the spring Yseat channel |08, the channel being stabilized by a clip |09 embracing the outer extremities of the Vweb |01 andV framing web ||0. YThe clip in this form is bolted in posi-v tion. Y Y e In most of the forms, the end portion of acuter oi spring plank of ordinary form may be utilized1 Y as the channel spring seating member and'ifor carrying the brake beamguard, guide, or supyto f port device, while in others a special spring s-eat Vmember is provided. Alsoin most of the forms hook means is provided for stabilizing the bolster spring seatk against a tendency to tilt due to the overhanging weight vof the break beam guard, guide, or support device.V In Figures 1 to 5, in particular, at least al portion of the weight of the guard, guide, or support device is carried'by a special lip or jaw formed on the guard, guide, or support bracket and overlying the supporting truck part. In Figures 9 to 14inclusive, the cutoff spring plank is itself specially shaped to form all or a part of the mounting for the brake beam guard, guide, or support member. e

The invention is not limited to the structures illustrated and described but may be modified in various respects as will occur to those skilled in the art, and the exclusive use of all such modications as come within the scope of the appended claims is contemplated.
